[PATCH 0/5] ASoC: SOF: Intel: don't download firmware at each resume
by Pierre-Louis Bossart 25 Jan '22

25 Jan '22

After the first firmware boot, the firmware is capable of saving/restoring its context to/from IMR (Isolated Memory Region, set aside by BIOS on startup). This capability improves the resume speed. Due to an unexplained issue on Up2 boards, this capability is disabled on ApolloLake. For backwards compatibility, the regular boot flow is used with older firmware. For added peace of mind, a kernel module parameter is provided to force the regular boot flow - this shouldn't be necessary since we've been testing these patches for 6+ months.

[PATCH] ASoC: soc-generic-dmaengine-pcm: separate max_buffer_size assignment
by Shengjiu Wang 25 Jan '22

25 Jan '22

The config->pcm_hardware may be NULL when config->prealloc_buffer_size is not zero, so it is better to move max_buffer_size assignment under a separate condition.

[PATCH v3 0/2] ASoC: add support for TAS5805M digital amplifier
by Daniel Beer 25 Jan '22

25 Jan '22

This pair of patches implements support for the TAS5805M class D audio amplifier. This driver, and the example configuration in the device-tree file, were originally based on a 4.19 series kernel and have been modified slightly from the tested version. This resubmission differs from v2 as follows: - The redundant mutex has been removed - DSP configuration is loaded as a firmware image, rather than directly from the device-tree - The volume control returns non-zero when the values have changed, as required - Some corrections to device-tree example Daniel Beer (2): ASoC: add support for TAS5805M digital amplifier ASoC: dt-bindings: add bindings for TI TAS5805M. .../devicetree/bindings/sound/tas5805m.yaml | 56 ++ sound/soc/codecs/Kconfig | 9 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tas5805m.c | 567 ++++++++++++++++++ 4 files changed, 634 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/tas5805m.yaml create mode 100644 sound/soc/codecs/tas5805m.c -- 2.30.2

[PATCH v2] ASoC: codecs: Check for error pointer after calling devm_regmap_init_mmio
by Jiasheng Jiang 25 Jan '22

25 Jan '22

Since the possible failure of the devm_regmap_init_mmio(), it will return error pointer and be assigned to the regmap. Then the error pointer will be dereferenced. For example rx->regmap will be used in rx_macro_mclk_enable(). Therefore, it should be better to check it.

The devm_regmap_init_mmio() may return error pointer under certain circumstances, for example the possible failure of the kzalloc() in regmap_mmio_gen_context(), which is called by devm_regmap_init_mmio(). Then the error pointer will be dereferenced. For example rx->regmap will be used in rx_macro_mclk_enable(). Therefore, it should be better to check it.
